Reaction Steps

A mixture of 6-bromoindoline (750 mg, 3.79 mmol), 1-(bromomethyl)-3-fluorobenzene (697 pt, 5.68 mmol) and cesium carbonate (1.851 g, 5.68 mmol) in N,N-dimethylformamide (7.573 mL) was stirred at 110° C. for 2 hours. The mixture was cooled, diluted with 100 mL ethyl acetate, washed with water and brine, dried over magnesium sulfate, filtered and concentrated. Purification by silica gel flash chromatography (Isco®, Redi-Sep® column), eluting with a gradient of 2-50% ethyl acetate/hexane, afforded the title compound. LCMS: 306 (M+H)+.
